Nitrogen in tires....(Warning. Unscientific test inside)

My 2010 came with green valve caps. I understand that this means my tires are filled with nitrogen.

The tires on my Taco have lost pressure at a slower rate than any other tires that I recall having, so maybe there is something to filling them with nitrogen.

Also, if Toyota is going to put nitrogen in the tires, they must have a reason. I would think that it is more expensive than air.

 

The Chevy dealer I work at is charging $69.95 per vehicle for nitrogen. What a scam.

 

sorry, I had to say it

jk cool test, now I know, regular air is just fine.

 

Don't forget about local atmospheric pressure. It changes with altitude and weather.

 

I used to use nitrogen to check for leaks in A/C units and that stuff was cheap you probably could fill dozens of tires with one cylinder never thought of putting it in my tires. It's a great way to get people to spend money the profit must be 500% like any thing else if you believe it works it does I get all the nitrogen I need from my compressor.

 

Hey Chris what kind of dryer does your friend have?
Refridgerated or Dessicant?
The dessicant will drop moisture a bunch more than the refer type.

I was involved with a sprint car for about 10 years and when we ran PIR 1 mile asphalt oval we used N2 to try and keep the tire growth to a min. On the dirt, naww just go with air, we did use auto bleeders in the rims to let off excess air over what we wanted to keep in the tire.

Did you boys vacuum out all the atmosphereic pressure air before filling up the tanks?
Check for any leaks on your tanks, fittings, guages, ect?
Don't forget guage accuracy + or - can be 1-10% depending on the quality of guages.
So much to conssider to remove a little H2O from the mix.

 

i had a girl up in central cali near Mammoth Mtn tell me that she could not take air out of her tires because it had nitrogen in. SHe only gets it fill up at costco. she was stuck mind you with bald ass tires. I am almost laughed .

 

I was in a Goodyear tire store a few years ago. A white haired old lady came in and asked the counter people if they had nitrogen for her tires. They said no. The old lady left the store and drove away. The counter guys looked at each other and said "Must be a race car driver" and we all cracked up.

Nitrogen....

 

I had this arguement with the Mitsubishi dealer about 5 months ago when my wife's Outlander TPMS sensor light activated. She took it to the dealer and they told her it would be $25 to fill the tire with nitrogen. Luckly she called me and I told them they are insane. The dealer went as far as to tell me they would not cover the warranty for the tires unless they were filled with nitrogen. I quickly reminded the service manager that Mitsubishi doesn't cover the tires, the tire manufacturer covers the tires. Needless to say, I had my wife stop at the local gas station to fill the tire with regular air for 25 cents. I then called the local tire shop to see if there was any merit in nitrogen vs air, and they adivised me that the tire manufactures do not back the "nitrogen is better" theory.

 

There is one more thing that bothers me about the nitrogen thing what do they do with the air and moisture that is all ready in the tire before they put the nitrogen in? Even a flat tire has air in it.

 

we had thought about doing this but the cost to benafit was so small in way of benafit it was not worth it

the life of the tpms senors are about 5yrs anyway before the battery gos bad or should be replaced most tire shops will say that as the dealer also

 

^^^ This

Most people forget that

 

I say its a gimmick. Air is fine with regular maintenance, i'm out there anyway checking other things.

 

I run N2 in my tires, I also work for an air separation plant. You can get all the air and moisture out of your tires by purging with N2. I noticed a huge difference between pure N2 and air when I put N2 in my lift shocks. Before I would fill em up and a week later the ass of the truck would sag. Then I put N2 in em' and they never leaked again, at least over the course of a year. I put N2 in my tires cuz it's free for me. If someone told me they'd charge me $70 dollars to do it I'd laugh too. There are lots of benefits of running a pure gas in your tires or whatever, but if the money ain't right then eff that. What you should really be testing is the benefits of running HELIUM in the tires. I bet that would give you better gas mileage.

 

So If hydrogens lighter then air, If I run pure hydrogen in my vehical tires, they will actually lower to total weight of my truck and i'll be both faster and get bettter MPG??

 

If you do it right your wheels can even look like they are on fire.
